Often, water heaters are purchased for use in summer cottages, for work “in the field.” Accordingly, there may be no centralized gas supply in dacha cooperatives and settlements. There is a way out – install an electric water heater or choose a geyser with the ability to connect to a cylinder. Can a gas column work from a gas cylinder? Yes, if the manufacturer has provided such an option. How to connect it and what fuel to use – you will find answers to these questions below.
You can also reconfigure an existing column. To do this, carefully read the instructions in the final part of the article.
Types of fuel for the dispenser
The substances used to heat water are called propane and butane. These are derivatives released during the processing of “black gold” – oil (gasoline, gas). Both pure technical butane and a mixture of butane with propane in their winter or summer version are used.
When compressed, gases become liquid and occupy a smaller volume. That is why this type of fuel is often called “liquefied”.
When the pressure is reduced, the gas changes into a vapor state. Since the gas tends to expand at high temperatures, the cylinder is usually filled to 85% of its full volume. If you think that you are “not topped up” with fuel, this is for your own safety.
Fact! Above the liquid gas there will always be a layer of gas in the vapor state.
Gas cylinder – 100% country option
Often a flowing water heater powered by bottled gas is the only way to heat water for a summer residence. Of course, no one canceled the “summer shower” with natural heating from the sun, but what to do in winter? Output – boiler or geyser.
As for the electric water heater, it is not always possible to make a choice in its favor for a simple reason: not all holiday villages have an ideal electrical network that would work without failures and would not annoy with power surges. Partly to blame for this are those who use electric motors for irrigation, electric saws, air conditioners and other powerful appliances. A boiler or an electric instantaneous heater is not always a profitable solution.
It is not a problem to get a cylinder with a gas mixture. Moreover, most domestic manufacturers (and not only) produce gas equipment that works regardless of what gas is used – ordinary or liquefied.
Connecting equipment to the cylinder
Before you start connecting the equipment yourself, make sure that the model really fits.
On a note! There are many manufacturers producing columns that can run on “liquid” gas. For example, one of such firms is Neva. Read more about it on page “Geysers Neva».
Other brands of acceptable equipment: Vaillant, Bosch (almost all recent models). The instructions for the Bosch speakers indicate that a 50-liter cylinder is enough for 10 hours of stable operation at a power of 25 kW. A conversion kit for Bosch speakers is available from an authorized service center.
If it is necessary to carry out work on the readjustment of equipment, the replacement of collector nozzles and the assessment of the tightness of the joints, they must be done strictly according to the rules. Nozzles should be smaller in diameter: as in gas stoves, the pressure given out by liquefied gas reducers is 2-3 times higher than when natural gas is supplied through pipes. At the same time, the calorific value of liquid fuel is 1,5 times stronger than that of natural gas.
On the equipment, you need to put the date of the alteration – the day, month and year. The type of gas suitable for use is also indicated.
The scheme for connecting the cylinder to the GC requires it to have a reducer with pressure stabilization of 300 mm of water. Art. and a minimum vapor phase capacity of one cubic meter per hour.
Parameters of the hose connecting the gas equipment with the fuel tank:
- 250 cm – minimum length;
- 1,2 cm is the least acceptable internal diameter of the tube.
Important! When mounting the hose tube, do not bend or twist it in any way. Even if a bend is required, use adapters and keep an eye on the radius – it cannot be less than 9 cm along the outer arc. And also do not bend the hose earlier than 5 cm from the end of its tips.
Please note that the forums on the network contain information of the following nature: if you reconfigure the column correctly and carry out the work without flaws, problems with water pressure may occur and the column will not start. Then you will need an additional installation of a pressure pump.
When installing a shut-off valve, remember that it must be easily accessible so that the user can quickly close it in the event of an emergency.
After completing the installation work, check the tightness of the connections and conduct a test run of the equipment.
